FWIW, backup batteries are typically good for about 5-8 years, depending on playing frequency (the less the synth is powered on, the more the battery is drained), the storage temperature, and other factors. If the AN1x is five or more years old -- and it probably is -- then replacing the battery is not unexpected. I do think that the dealer should have let you know that this was the case, but I don't think it's worth cancelling the sale or anything. Almost any AN1x purchased today could be a candidate for battery replacement within a few months.
Replacing the battery is a very simple task for a repair tech to perform. It shouldn't cost more than an hour of repair time, plus the cost of the battery ($3-5US).
Regards,
-BW
